SERVO MOTOR CONTROL APPARATUS AND CONTROL METHOD

摘要

A servo motor control apparatus has a feedback loop. When an oscillation detection signal indicates no detection of oscillation, a parameter operating section gives an updating section an operational instruction to set a control parameter in accordance with a supplied set value. When the oscillation detection signal indicates detection of oscillation, the parameter operating section gives the updating section an operational instruction to set such a control parameter as to narrow a frequency band width of the feedback loop.
